Answer 1

？？正常情况缺return   而且你这个代码没有输出打印函数吧，要的是输出title？

 

from urllib.request import urlopen
from urllib.error import HTTPError
from bs4 import BeautifulSoup
def getTitle(url):
    try:
        html=urlopen(url)
    except HTTPError as e:
        return None
    try:
        bsObj=BeautifulSoup(html.read(),"html.parser")
        title=bsObj.h1
        return title
    except AttributeError as e:
        return None
title=getTitle("https://mail.qq.com/")
print(title)
